You may lose the tabs which separate the fields, however.
would you be able to break this down pls so i can understand how it's achieving the result? I have a similar problem and i think i should be able to tweak this if i can understand it. thanks

CMIGREP(1)						      General Commands Manual							CMIGREP(1)

NAME
cmigrep - search in ocaml compiled interface files SYNOPSIS
cmigrep <options> <module-expression> DESCRIPTION
This manual page documents briefly the cmigrep command. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page. cmigrep allows to search for information in compiled interfaces of OCaml modules. By default, the search applies to the modules described in the .cmi files in the curent directory and in the ocaml standard directory, but this can be changed with the -I option (see below). The argument <module-expr> can be an exact module name, or a shell wildcard. Multiple modules can be specified. Example: "ModA ModB Foo*.Make" means to search ModA, ModB, and any submodule Make of a module that starts with Foo. OPTIONS
General Options -I directory Add directory to the search path for modules -package packages comma separated list of findlib packages to search open modules comma separated list of open modules (in order!) -help, --help display list of options Search Patterns -t regexp print types with matching names -r regexp print record field labels with matching names -c regexp print constructors with matching names -p regexp print polymorphic variants with matching names -m regexp print all matching module names in the path -e regexp print exceptions with matching constructors -v regexp print values with matching names -o regexp print all classes with matching names -a regexp print all names which match the given expression SEE ALSO
Examples can be found on /usr/share/doc/cmigrep/README. AUTHOR
